About two hours into the podcast, which can be seen on YouTube, Musk inhales from what the host says is a combined marijuana-tobacco joint, which Rogan notes is legal.
"I'm getting text messages from friends saying, 'What are you doing smoking weed?' " he said.
The 47-year-old billionaire later said he wasn't a "regular smoker" of marijuana because he doesn't find it "very good for productivity". "I don't actually notice any effect ..."
Morton's departure further roiled the company which has been under heightened scrutiny since Musk's chaotic announcement on August 7 on Twitter that he was considering taking Tesla private, a plan that was reversed two weeks later. A spokesperson for Tesla did not immediately return request for comment regarding Toledano's standing at the company.
Tesla noted in a statement to Reuters that Morton opted to depart from the company due to his discomfort with the level of public attention and Tesla's overall pace of work.
Musk said he was not as anxious about artificial intelligence than he was previously after "taking a more fatalistic attitude".
The aura of weed has surrounded Musk before.
"I think the future in where we are a space-faring civilization out there among the stars, that is very exciting", Musk said.
Incidentally, being recorded in California, it was entirely legal.
Viecha also restated Tesla's forecast that it will build 50,000 to 55,000 of its Model 3 sedans in the current quarter, and indicated the company's working capital will improve as production increases, Spak wrote.
